Welcome to California Engineering Contractors

California Engineerin Contractors - Bay Bridge Cut in Two Recognized as one of the West Coast's most reputable and reliable heavy construction contractors, California Engineering Contractors Inc.(CEC) regularly and successfully tackles difficult, complex projects with skill and apparent ease, consistently delivering top-quality work on time and within budget. The company's well known focus on technically demanding and schedule-driven projects has characterized CEC since it opened its doors for business in 1972, starting with just a small amount of savings, a pickup truck and two employees.

The company's experience now includes virtually all types and sizes of public works projects - railroad construction, seismic retrofit and rehabilitation of major structures, bridge construction, marine construction, flood control structures, tunnel retrofit/rehabilitation, and other infrastructure-related projects.

Spans Become Ships...Again

When CEC brought down the Carquinez Bridge spans, they became the subject of a National Geographic documentary.

Bay Bridge Steel Recycling Continues

The Bay Bridge Steel Program, being administered by Oakland Museum of California (OMCA), was created in response to significant public interest from Bay Area artists and creative communities in making steel from the bridge available for repurposing and reuse. The program’s intent is to preserve elements of the original 1936 East Span of the Bay Bridge. Click here to learn more.
